Penko Vox: Japanese Privacy Policy
Last updated: September 29, 2026
Penko Vox: Japanese runs entirely on your computer. We don't collect your personal data: no accounts, telemetry, analytics or ads.
Who we are
Penko Vox: Japanese is made by Penko Software, an independent software studio. Questions about privacy: contact@penkosoftware.org.
What happens on your computer
- The AI, speech recognition and speech synthesis all run locally on your computer.
- Microphone audio is processed on your computer. It is never uploaded and never stored.
- Your conversations, vocabulary and progress are saved in a local file, saveData.json, which you can delete at any time.
- No accounts, telemetry, analytics or ads.
- No internet connection is needed to use the app.
What Steam handles
Penko Vox: Japanese is sold through Steam. Purchases, achievements and, if you turn them on, Steam Cloud saves (which sync your save file) are handled by Valve under the Steam Privacy Policy: https://store.steampowered.com/privacy_agreement/. We don't receive your payment details.
This website
Our website is hosted on GitHub Pages. Like most web hosts, GitHub may log technical information such as your IP address to keep the service secure and running (see the GitHub Privacy Statement). We don't have access to these logs and don't use them. The site stores your chosen language and theme on your device, and has no cookies, analytics or trackers. Screenshots are served from our own site; the trailer streams from Steam's servers only after you press play. Links to Steam include a campaign tag so Steam can show us which of our pages referred a visit; it contains no information about you.
Children and schools
Because the app doesn't collect personal data, it is suitable for classroom use, including with children. Schools and universities can contact us at contact@penkosoftware.org for details, classroom pilots or institutional licences.
Changes and contact
If this policy changes, we'll update it here and change the date at the top. Questions or requests: contact@penkosoftware.org.
